the white one I think is old dutch cleanser mine. It has a pretty cool history http://deathvalleyjim.com/2012/04/10...hy-camp-32812/
The Old Dutch Cleanser Mine began operation under Cudahy Packing Company in 1923. The primary mineral that was mined was pumicite, which is a variety of pumice (highly pressurized rock that is violently ejected from a volcano, it is formed when lava and water are mixed). Cudahy Packing utilized this material for the manufacturing of Old Dutch Cleanser, a domestic kitchen and bathroom scouring powder that was highly popular and well know in the USA. Old Dutch Cleanser is still manufactured today, however the mining location for pumicite was relocated in 1947.
